Majeti Narasimha Vara Prasad is currently Emeritus Professor, School of Life Sciences, University of Hyderabad, Hyderabad, India. He has made outstanding contributions to the fields of bioremediation, bioresources, biomass energy sources, bioeconomy and to the broad field of environmental biotechnology, all of which are his main areas of expertise. Dr. Prasad has served the Ministry of Environment, Forests and Climate Change, Government of India in various advisory committees on biodiversity conservation, ecosystem services, pollution control and abatement, environmental information systems and bioremediation of contaminated sites. He is an active visiting scientist in several international universities. Dr De Campos Favas is a professor in the Department of Geology of the University of Trás-os-Montes e Alto Douro as well as a member of the Marine and Environmental Sciences Centre (MARE) from the University of Coimbra. He has been involved in 10 research projects. He is author and co-author of 29 peer-reviewed papers in scientific journals and 136 papers in conference proceedings, has 19 book chapters and 2 books published. His main areas of research are: heavy metals and arsenic contamination (soil, sediment, water); acid mine drainage; bioaccumulation of metals in plants (aquatic and terrestrial environments); hyperaccumulator plants; phytoremediation; bioindication; restoration of degraded mine areas. She is the leader of the Ecosphere Resilience Research Center, Faculty of Applied Science at the University of Sri Jayewardenepura, Sri Lanka, Visiting Associate Research Professor, National Institute of Fundamental Studies, Sri Lanka and an Adjunct Associate Research Professor at the University of Southern Queensland, Australia. Dr. Vithanage’s research approach builds on enabling measurements of concentrations and reaction rates in environmental samples for key/emerging pollutants in the environment in order to assess their fate and transport to discover solutions to remediate those using different geo/bio/nano materials. Dr. Vithanage is particularly interested in elucidating the mechanistic understanding of release/remediation of pollutants with contrasting physical and chemical properties that can be used to obtain insights into environmental partitioning, chemical persistence and ultimate accumulation in biota. To this end, her current research interests are focused on monitoring atmospheric deposition, landfill leachate, water and soil for pollutants, develop and enhance the properties of biochar, nano/geo substances and composites as material for environmental remediation. She has received several awards from,TWAS-NSF Award for the Young Scientist, American Geophysical Union, Presidential Awards for Publications, Awards for science popularization and for post graduate supervision by the National Science Foundation, Sri Lanka. She is a Young Affiliate of the Third World Academy of Sciences. She was the Chairperson of the Young Scientists Forum on the National Science and Technology Commission of Sri Lanka in 2017. Currently, she is the President of the Engineering, Architecture, Surveying Section of the Sri Lanka Association for the Advancement of Science. She has contributed more than 80 Science Citation Indexed journal articles and 25 book chapters. Her citation record is now passed 2300 with an H index of 24. Dr.S.Venkata Mohan is working as Principal Scientist in CSIR-Indian Institute of Chemical Technology, Hyderabad since 1998.
